ok small scenario. NATO takes Ukraine in as a member. Ukraine, trusted by NATO and the U.S., ends up joining the R.U.S.S.R. or the reformed U.S.S.R. Vladimir Putin suddenly has inside people in the NATO forces. The whole concept of NATO was to create and keep peace along with removing fear. There WILL BE fear from more than one country that Ukraine will create relations like that to Russia.

That scenario shows the most incredible lack of understanding of NATO i've ever witnessed in my life. Seriously, I think it's time you start asking for a refund for your college classes.
